Be it known that I, EMORY B. OUSHING, of Boston, in the county ofSuilblk, and State of Massachusetts, have'invented a new and usefulMachine for Burnshing the Edges of thc Soles of Boots and Shoes; and Ihereby declare that the following is a full andexact descriptionthereof, reference Abeing had to the accompanying drawings, and to theletters of reference marked thereon, making a part of thisspecification, of which- Figure 1 is a side view of the machine. Y

Figure 2 is a top view of the machine.

' Figure 3 is a front end view of the machine.

Figure 4 is a. longitudinal section of the machine.

Figure 5 is a transverse section of the burnishing-tool and thesliding-box, Ste.

Figure 6 is a-front en d view ot" the fast pulley, with its cam-groove,85o.

A represents the'frame of thermachine, supporting the head-stock B; C,its arbor; I), its fast pulley, and E'its loose pulley; a, itscam-groove in the faceof the pulley D; I), a bent arm, workingin'thegroove a; c, a sliding-box of the arbor C; b', a lever for operating theadjusting-slide e; the burnishing-tool; e, its adjustingslide or gauge;fff, the clutches; g g, their pulleys; F, their shaft; t', a bent lever,working in the clutch f; z', another bent lever, operating the lever h;j, a chain attached to the Vibrating standard k; Z, the treadle; Im, itsconnecting-rod; un, slotted arms of the standard k; o, itsverticalshaft; p, its lower gear or scored Wheel, operating against theelastic -wheel q ou the driving-shaft F; 7', the elastic wheel on theupper end of the shaft o, working against the gear or scored wheel d',fixed on the horizontal sha-ft s, supported by the upper part of thestandard k; t, the crossvhead, fixed to the other end of the shafts,this cross-head carrying the sliding-rest u, dove-tailed to thecross-head t; o, the sliding-arm to enter the'last w; fr, the screwforregulating the rest u and sliding-arm v; y, the handle of thevibrating standard 7c.

In ordenthat others may more fullypunderstand the nature and use of myinvention, and be enabled to manufacture the same, I will proceed toexplain it.

Burnishing the edges of the solesof bots and shoes requires skill andmuch time. My invention performs this work with skill and rapidity, andhereby explain the various parts of the machine and their uses, and themanner in which the burnishing is done. v I

By examining the accompanying drawings it will be perceived that Arepresents'the framework, and supports the machine; that between theupper part of the framework or head-stock B B are two pulleys, the fastpulley D, and the loose pulley E; that the revolution of the fast pulleycarries with it the arbor C and the burnishingrodd; that at the end oftho fast pulley D, next the arbor C, is a groove,"n which plays the bentarm b, which is fastened to one of the sides of the head-stock; thisgroove is somewhat eccentric, (see lig. 6 in drawings so. that, when thepulley revolves, the bent arm, sliding in the groove, causes a thrust orsliding motion back and forth, which nearly resembles the motion of thehand in burnishing; that above the arbor C is the sliding-box e; thissliding-box has within it the adjusting-slides or gaugese, and isoperated by u lever, b, which acts on the enclosed cam; that theburnisher d also is adjustable, and operates with the gauges, so thatbetween the gauges the edge of the sole is held fast while it is beingburnished. Figs. 1, 3, and 4 represent the standard lc, and the variousparts connected therewith. Motion is communicated to it by the shaft F,driven by the pulleys g g; and this motion is further regulated byfootand hand motion upon the treadle Zand the handle y. It will beperceived that the standard has two slotted arms n it, through whichpasses the shaft F, and that, by means of the trcadle, the standard canbe raised Vand lowered at pleasure, playing in these slotted arms.Outside of the standard is theA shaft o, which is driven by gear or a.scored wheel, operating against the elastic wheel at the end of thedriving-shaft I". Instead of the elasticwheel, gear or a scored wheelmay be used. The upper part of this shaft has on Ait an elastic band orgear or aiscored wheel, connected with the gear or scored wheel d',fixed on the horizontal shaft s, which is supported by the upper part ofthe standard lc. .lhe horizontal shaft hasv a cross-head, t, fixed atone end, carrying on it a sliding-rest, for the toc of the boot or shoe,dove-tailed to it. Fig.`4 shows the sliding-arm v, which enters the lastw; and

t this is regulated by the screw l7;, which is held by the two arms ofthe cross-head t at cach extremity. By

casu

turning the screw in one direction it operates on the sliding-arm n, andthe toe of the boot is brought tightly down upon the rest u, holding itfirmly when ready for burnishing; but by vturning the screw in thecontrary direction the toe is loosened, and can be taken from the rest,the. Figs'. 1 and 4 show the cha-in j, fastened to the standard and theframe of the machine. This keeps the standard from falling too far toeither side. Figs. 1 and 2 shew the pulleys g g', which give motion tothe shaft F. fff, also, are clutches, worked by a bent lever, L; andthis lever is worked by :mother lever, z'. When the lever z' moves theclutch j" from the left to the right the clutch f" operates uponthepullcy g; and when the clutch f 'is moved from theright to the leftby the lever i the clutch f operates on the wheel y; and cach running inthe opposite direction the cross-head t carries the boot or shoe to beburnished in theA one or the other direction, as desired.`

Having thus described the various parts of the machine, it remains toshow its operation. Suppose the lever z' is at the left, causing the'lever 7L to fasten the clutch j" upon the pulley g, andsuppose theburnisher and gauge fastens upon the edge ofthe sole ofthe b oot orshoe, near the heel upon the shank, the action of the shafts F, 0, and swill cause the cross-head t to carry the boot or shoe from the heelaround over Vthe toe to the heel on the other side, from right to left,quickly performing the operation of burnishing. Loose the screw a', andtake off the boot and put on another. Change the motion by carrying thelever z' from left to right, which causes the clutch f to fasten uponthe pulley nf/,land the opposite or return motion isk effected, and thecrosshead, carrying the boot, returns backward to the first position,hurnishing from left to right. In this operation the workman keeps hisfoot upon the tread'le, so that the boot is pressed up and loweredconstantly under -the hurnisher, having one hand, also, upon the handley of the vibrating standard to guide the work. To obtain the oppositemotions from the pulleys g g one pulley is moved by a cross-band, andthe other by a straight band.

By the use of this machine several pairs of boots or shoes maybeburnished while one pair is burnished by hand, Athus gaining time andlessening expense. Itis, therefore, of great practical utility, novel,and useful to the publie.

l do not claim a heel-burnisher, but only a machine to burnish the edgesofthe soles.

What I claim as my invention, and desire to secure by Letters Patent, is

l. I claim the standard 7c, and the combination and arrangement of themachinery connected therewith, namely, the treadle c, the shafts l?, o,and s, and their gearing, whereby the hand and foot movements aresecured, so that the boot or shoe will follow theburnisher,substantially in the manner and for the purpose above setforth.

2. I claim the cross-head t, in combination with the screw x, the. restu, and the sliding-arm v, whereby any-sized boot or shoe is held, andalso whereby the motion following. the burnisher is secured,substantially in the manner and for the purpose above set forth.

3. I claim the combination and arrangement of the clutches fff/l withpulleys g g, whereby is secured the change motion of the cross-head, sothat the boot or shoe can turn from one shank to the other,substantially in the manner and for the purpose above set forth. I

4. I claim the combination and arrangement of the gauges or guides e tothe hurnishing-tool d, which do not revolve with the burnishing-tool,combined and in connection with the cam movements in thesliding-boxc,whereby the guides are usted 'to the edges Yof the soles, substantiallyas set forth.'

5. l claim the combination and arrangement of the cam-groove a and thebent arm b, working in the camgroove in the face of the pulley D,whereby is secured the thrust or hand-like motion, substantially in themanner and for the purpose above set forth.
